Ndi waya uti womwe umatentha ngati mawaya onse ali ndi mtundu wofanana?

Kugwira ntchito ndi mawaya amoyo ndi ntchito yovuta komanso yowopsa, ndipo katswiri aliyense wamagetsi angakuuzeni kufunikira kodziwa kudziwitsa mawaya amoyo kuchokera ku mawaya osalowerera ndale. Simukufuna kuzisakaniza kapena zingayambitse mavuto amtundu uliwonse, omwe ambiri amakhala ozungulira. Ngakhale mawaya nthawi zambiri amakhala amitundu kuti azindikire mosavuta, nthawi zina samatero. Izi zitha kukhala chifukwa chosasankha bwino mawaya m'nyumba mwanu kapena chipangizo chomwe wopanga adasankha mtundu womwewo wa waya.

Mosasamala chifukwa chake, muyenera kudziwa njira zomwe mungagwiritse ntchito kuti muzindikire waya wotentha pamene mawaya onse ogwira ntchito komanso osalowerera ndale ali ndi mtundu womwewo. M'nkhaniyi, tikuphunzitsani momwe mungachitire izi, choncho pitirizani kuwerenga.

Pochita ndi mawaya amagetsi amtundu womwewo, njira yabwino yodziwira yomwe ili yotentha komanso yosalowerera ndikugwiritsa ntchito multimeter yabwino. Lumikizani ku mawaya molingana ndi malangizo a wopanga ndipo waya wokhala ndi voteji mkati mwake udzakhala waya wotentha.

Kumvetsetsa kusiyana pakati pa mawaya otentha ndi mawaya osalowerera

Kusanthula mawu osavuta kudzakuuzani kuti waya wotentha ndi womwe umagwira ntchito pamwamba kuposa kutentha. Zikakhala kuti sizikugwira ntchito, mawaya onse ndi mawaya ozizira mpaka mutayendetsa magetsi. Kuyendetsa magetsi kumatulutsa kutentha, ndipo waya wonyamula magetsi amatentha. Ichi ndichifukwa chake waya wamoyo umatchedwanso waya wotentha. (1)

Mu dongosolo limodzi la gawo limodzi, mudzakhala ndi mawaya awiri omwe akudutsa mu dongosolo, imodzi yomwe imanyamula magetsi. Uwu ndi waya womwe ungalumikiza switch yanu ku zida monga babu, fani, kapena zida zina zamagetsi. Pali zochitika ziwiri zomwe mumawona mukamagwira ntchito ndi mawaya achikuda. Zitha kukhala mawaya ofiira ndi akuda kapena akuda ndi oyera. Poyamba, waya wotentha nthawi zambiri amakhala wofiira, pamene, muzochitika zachiwiri nthawi zambiri zimakhala waya wakuda wotentha ndipo waya woyera ndi waya wosalowerera.

Komabe, ngati onse ali ndi mtundu wofanana wa waya, ndiye kuti mutha kupeza zosokoneza kudziwa kuti waya wamagetsi ndi wotentha komanso kuti ndi wachilengedwe. Mwamwayi, pali njira zomwe mungagwiritse ntchito kuti muzindikire mawaya molondola kuti musawalumikize ku malo ogulitsira ndi zida molakwika.

Kuwona kuti waya wotentha uti pamene onse ali ndi mtundu wofanana

Mutha kuyesa ngati waya wamagetsi ndi wamoyo kapena osalowererapo pogwiritsa ntchito njira zingapo. Komabe, njira zambiri zomwe zilipo zili ndi njira zina zotetezera. Izi zikutanthawuza kuti munthu wokonda kuchita masewera olimbitsa thupi sayenera kuzigwiritsa ntchito chifukwa zingayambitse dera laling'ono kapena, poipa kwambiri, imfa ya munthu amene amalumikizana ndi mawaya, chifukwa mphamvu yamagetsi ndi yakupha.

Chifukwa chake, tifotokoza mwatsatanetsatane njira yokhayo yomwe ili yotetezeka kugwiritsa ntchito komanso kuvomerezedwa ndi chikhalidwe chake.

Njira yomwe tikukamba ndikugwiritsa ntchito multimeter. Kudziwa kugwiritsa ntchito kungakhale kothandiza kwambiri pazochitika zosiyanasiyana. Pankhaniyi, akhoza kudziwa mosavuta kuti ndi chiyani poyendetsa magetsi akudutsa mu masensa ake.

Onetsetsani kuti mukudziwa momwe multimeter imagwirira ntchito musanaganize zogwiritsa ntchito kuyesa mawaya otentha ndi achilengedwe.

Tsopano popeza muli ndi multimeter yogwira ntchito, muyenera kutsatira izi kuti mudziwe waya wotentha ndi waya wosalowerera.

1. Khazikitsani ma multimeter kukhala AC voltage mode, yomwe nthawi zambiri imatchedwa HVAC, VAC, kapena 200V. Izi zitha kusiyana kutengera dziko lomwe muli komanso mtundu womwe mumagwiritsa ntchito. Onetsetsani kuti mwagula mita yabwino ya digito kuti musaifupikitse mwangozi ndikuiwononga.
2. Gwirani kafukufuku wofiyira pa multimeter ku imodzi mwawaya, ndiyeno gwirani kafukufuku wakuda pazitsulo zazitsulo, zomwe nthawi zambiri zimapangidwa ndi zitsulo. Mlanduwu udzakhala ngati poyambira, kutanthauza kuti mukangolumikizana ndi waya wamoyo, madzi akuyenda pansi ndipo sichidzavulaza ma multimeter kapena inu.
3. Onani zowerengera zomwe zikuwonetsedwa pa multimeter yanu. Ngati muwona kuwerengedwa kwa 0 kapena pafupi kwambiri ndi iyo, ndiye kuti waya womwe mukugwira nawo ndi kafukufuku wofiyira ndi wosalowerera mu mtundu. Komabe, ngati kuwerenga pa multimeter yanu kuli pafupi ndi 100-120 volts, ndiye kuti mukugwira waya wamoyo ndi manja anu. Mtengo uwu ukhozanso kukhala pakati pa 200 ndi 240 malingana ndi kayendetsedwe ka magetsi m'dziko lanu. (2)
4. Yang'ananinso mawaya kuti muwonetsetse kuti ndi iti, ndiyeno lembani waya wamoyo pomangapo kachidutswa kakang'ono ka tepi yamagetsi. Mukhozanso kugwiritsa ntchito njira zina, koma onetsetsani kuti palibe iliyonse yomwe ingawononge waya.

Kufotokozera mwachidule

Magetsi ndi chinthu choopsa, ndipo simupeza mwayi wachiwiri wokonza zolakwika zanu ngati musokoneza chinachake. Ichi ndichifukwa chake ndikofunikira kwambiri kudziwa mawaya omwe ali ndi moyo komanso omwe salowerera ndale. Kulumikizana kolakwika kumatha kubweretsa zovuta zamitundu yonse zomwe simukufuna kuziwona. Chonde tsatirani kalozera wathu mosamala ndipo onetsetsani kuti mwatsata malangizo onse otetezedwa.

Onani zina mwazolemba zathu pansipa.

• Momwe mungadziwire waya wosalowerera ndi multimeter
• Momwe mungasiyanitsire waya wolakwika kuchokera ku zabwino
• Momwe mungapezere dera lalifupi ndi multimeter
